There were multiple cast changes due to illnesses, both before and after the programs were printed. About a week before the performances, George Shirley replaced Peter Schreier. Karl Ridderbusch was replaced the day before the first performance by Theo Adam, who was in town for Wagner’s Siegfried at Lyric Opera; he sang the first two performances and Thomas Paul sang the third. Following the first performance, Wendy Fine was replaced by Sarah Beatty.

Following the Carnegie Hall performance, the work was recorded for London Records with multiple sessions in Chicago’s Medinah Temple. Ray Minshull was the producer and Kenneth Wilkinson, John Dunkerley, and Michael Mailes were the engineers.
